If Shaheen shows that he is healthy and actually does something in the preseason, great. I am not going to hold a spot for him to prove something during the season. If there are X TEs better than him at the end of preseason and they plan on only keeping X TEs, I have no problem cutting him. But at least give him a chance during the preseason.
Do you know which TE never got a chance due to injury but the Bears stuck with him? Miller. He was a constant IR player until he wasn't. He was pretty damn good when actually healthy.
